Technical Field

[0001] This utility model relates to the field of weft straightening machine technology, specifically a fabric weft straightening machine. Background Technology

[0002] A fabric weft straightening machine, also known as a fabric shaping machine or weft alignment machine, is a piece of equipment used in the fabric production process. Its main function is to correct the direction of the fabric and adjust its width and tension, thereby ensuring the neatness, uniformity, and quality of the fabric. Fabric weft straightening machines play a crucial role in weaving, dyeing, and finishing processes, especially for fabrics that are irregular or warped due to weaving, dyeing, or finishing processes. Weft straightening machines can help improve the appearance and quality of the fabric. Most existing fabric weft straightening machines are equipped with industrial cameras to inspect the fabric's appearance. However, these industrial cameras are mostly fixed in place and are exposed to the elements when not in use. They lack corresponding protective structures, and the dust, oil, and other contaminants in the workshop can pollute the cameras, affecting image quality and thus impacting the automatic detection and adjustment accuracy of the weft straightening machine.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, this utility model provides a technical solution: a fabric weft straightening machine, comprising: a fixed base 1, a movable base 2 slidably disposed on the top of the fixed base 1, a servo electric cylinder 3 disposed at one end of the movable base 2 for driving the movable base 2 to move laterally on the top of the fixed base 1; two equipment boxes 4 symmetrically disposed and fixedly connected to the top of the movable base 2, a plurality of bending rollers 5 rotatably connected between the two equipment boxes 4, a reducer for driving the bending rollers 5 installed inside the equipment box 4, a motor fixedly connected to the input end of the reducer, and a spreading roller 6 rotatably connected in the middle of the equipment box 4 and below the bending rollers 5. A geared motor is installed at the end; a U-shaped frame 8 is slidably disposed between two equipment boxes 4, and a straight roller 9 is rotatably connected inside the U-shaped frame 8; a fixed housing 14 is fixedly connected between the two equipment boxes 4, and a rotating frame 15 is rotatably connected inside the fixed housing 14. An LED light and an industrial camera 16 are fixedly connected to the middle of the rotating frame 15. The fixed housing 14 has an opening for the industrial camera 16 to take pictures. A rotating cover plate 17 is fixedly connected to one side of the bottom of the rotating frame 15. The rotating cover plate 17 has an arc-shaped structure and is concentric with the arc at the bottom of the fixed housing 14. It is used to block the opening and protect the industrial camera 16.

[0026] It should be noted that this embodiment includes a PLC controller and operation buttons. The fabric is wrapped around the outside of the curved roller 5 and the straight roller 9 along the S-shaped structure from top to bottom, as shown below. Figure 6As shown, multiple guide rollers 7 are rotatably connected between the two equipment boxes 4 to guide the fabric conveying. Guide rollers 7 are located at the top and bottom of the fixed housing 14, guiding the fabric vertically downwards within the fixed housing 14. During operation, the CCD camera collects the appearance information of the conveyed fabric. By combining the captured images with image processing algorithms, the surface of the fabric can be analyzed in detail, such as surface defects or foreign objects. When defects are found, the control system activates the alarm, and personnel simultaneously inspect and handle the issue. When the equipment is not in use, the corresponding drive mechanism drives the rotating frame 15 to rotate counterclockwise. The rotating frame 15 rotates the industrial camera 16 into the fixed housing 14. During the rotation, the rotating frame 15 drives the rotating cover plate 17 to rotate inside the fixed housing 14. The rotating cover plate 17 drives the sealing plate 18 to rotate, blocking the shooting port. At the same time, the rotating cover plate 17 causes the sealing plate 18 to fit against the top of the shooting port, thus placing the fixed housing 14 within the enclosed area formed by the fixed housing 14, the rotating cover plate 17, and the sealing plate 18, reducing the contamination of the industrial camera 16 lens by dust, oil, and other pollutants from the workshop.

[0027] In one embodiment, a linear guide rail is fixedly connected to the top of the fixed base 1, the movable base 2 is slidably connected to the linear guide rail, the servo cylinder 3 is fixedly connected to one end of the top of the fixed base 1, the output end of the servo cylinder 3 is fixedly connected to the movable base 2, and a web correction sensor 10 is fixedly connected to both ends of the bottom of the fixed base 1 on the side where the fabric is exiting. The web correction sensor 10 is an infrared sensor.

[0028] It should be noted that in this embodiment, the fabric passes through the bottom of the guide roller 7 located between the two equipment boxes 4. During the process of passing through, it passes through the bottom of the two correction sensors 10. The infrared sensor detects the position of the fabric edge. When the edge of the fabric corresponds to the correction sensor 10, the controller controls the servo cylinder 3 to drive the moving seat 2 to move away from the correction sensor 10 that issued the signal, thereby performing correction processing on the fabric conveying.

[0029] In one embodiment, a rotating shaft is fixedly connected to the middle of the rotating frame 15, and the rotating shaft is rotatably connected to the equipment box 4. A gear 20 is fixedly connected to the end of the rotating shaft. A dual-axis cylinder 11 is fixedly connected inside the equipment box 4. A rack 13 is fixedly connected to the output end of the dual-axis cylinder 11. An L-shaped metal plate that is slidably connected to the rack 13 is fixedly connected inside the equipment box 4 to support the rack 13. A limit switch that cooperates with the rack 13 is installed inside the equipment box 4. The rack 13 is meshed with the gear 20. The fixed housing 14 is slidably connected to the rotating cover 17. A sealing plate 18 is fixedly connected to the end of the rotating cover 17 to cooperate with the top of the shooting port.

[0030] It should be noted that, in this embodiment, when the industrial camera 16 needs to be rotated and adjusted, the controller controls the extension of the dual-axis cylinder 11. The dual-axis cylinder 11 drives the gear 20 to rotate via the rack 13. The gear 20 drives the rotating frame 15 to rotate via the rotating shaft. The rotating frame 15 drives the industrial camera 16 to rotate, and at the same time, it drives the rotating cover plate 17 to rotate around the rotating shaft, so that the rotating cover plate 17 slides along the inner wall of the fixed housing 14. When the rack 13 contacts the limit switch, the sealing plate 18 rotates to contact the top of the shooting port, thereby sealing the opening of the fixed housing 14 through the rotating cover plate 17 and the sealing plate 18, reducing the contact between dust and the industrial camera 16.

[0031] In one embodiment, the device housing 4 houses a lead screw module 12 that drives the movement of the U-shaped frame 8.

[0032] It should be noted that, in this embodiment, the lead screw module 12 includes a servo motor with an encoder and a lead screw fixed to the output end of the servo motor. The outer side of the lead screw is threaded with a slider that is slidably connected to the equipment box 4. The slider is connected to the U-shaped frame 8 through a metal plate. A groove is provided on one side of the equipment box 4 that is slidably connected to the metal plate, so that the straight roller 9 can be moved laterally by the U-shaped frame 8. The fabric tension can be adjusted by adjusting the distance between the straight roller 9 and the curved roller 5.
